多基站下基于DRL的RAN切片资源分配

In the fifth generation mobile communication, network slicing is used to provide an optimal network for various services. For the RAN slice scenario under multi base stations, the previous resource allocation methods can not meet the demand of slices when the number of slices changes, and are only suitable for specific scenarios. To solve this problem, this paper proposes a method to achieve the best resource allocation independent of the number of slices. This method first uses Ape-X method (a DRL method) allocate resources to slices, and then meet the needs of users through the resource mapping from slices to base stations and user resource allocation. The simulation results show that the proposed method can allocate resources according to the state and demand of slices, allocate the necessary number of RBs to meet the demand of slices, and is not affected by the change of the number of slices. At the same time, this method also has high general performance and scalability.
